TO ALL WHOM IT MAY CONCERN:

Be it known that I, WILIJAM STEPHENS, of Stephens Mills, in the county of Steuben, and in the State of New York, have invented certain new and useful improvements in Mill-Picksg and do herebyl declare that the following is a full, clear, and effect description thereof, reference being had to the accompanying drawings, and

to the letters of reference marked thereon.

In the annexed drawings, making a part of this specification, A and A represent two metallic bars, which form the head of the mill-piek. These bers are formed thick in the centre, end converge from i thence to euch end, as shown in Figure 1f Between these bars is placed the steel plate B, which is slightly longer than the bars A A, and sharpened et euch end, z, for cutting the stone. At the centre of this plate is an oblong slot, through which is passed the set-screw C from the upper bar A, and extends down into the lower bar A.` It will be seen that this bar cari be forced out more at either end, and there secured -in its place by this screw between the bars A A.

Having thus full)7 described my invention, wht I claim as new, and desire to secure by Letters Patent, is-

The combination and errang-ement of the bars A A', steel'plate B, and set-screw C, when constructed and used for the purposes specified.

In testimony that I claim the foregoing I have hereunto set my hand and seal -this 26th day-of March, 1867.

WILLIAM B. STEPHENS. [u 5.]
